Topic: two levels decision-making task

In our two levels decision-making task, monkeys had to select two options in two consecutive steps, with the first choice determining the reward values at the second. Choosing the lowest value at the first level gives the possibility to choose the greatest value at the second level. In this design, the animal can’t make wrong answers, but his behavior could reflect different levels of engagement in the task and thus, different degrees of optimization.
